3D is short for 3D, that is, 3D graphics. Displaying 3d graphics in a computer means displaying 3D graphics in a plane. Unlike the real world, the computer just looks like the real world, so the 3d graphics displayed on the computer will make people look real. One of the characteristics of the human eye is that when the distance is combined, it will form a three-dimensional sense. The computer screen is two-dimensional, and the reason why we can enjoy three-dimensional images is that the different colors and gray levels displayed on the computer screen make the human eye have optical illusions, and then the two-dimensional computer screen is perceived as a three-dimensional image. For example, if you want to draw 3d text, you will display the high-brightness color in the original position and outline it in the lower left or upper right position with low-brightness color, which will visually produce the effect of 3D text.
